       Setting the background to anything besides black confuses the intensity algorithm and will look terrible.

       The Intersection Momentary is a fun visualization defining the relationships between objects  with  Casey
       Reas, William Ngan, and Robert Hodgin. Commissioned for display at the Whitney Museum of American Art.

       A  surface filled with 100 medium to small sized circles. Each circle has a different size and direction,
       but moves at the same slow rate. Display:

           A. The instantaneous intersections of the circles.
           B. The aggregate intersections of the circles.

       The circles begin with a radius of 1 pixel and slowly increase to some arbitrary size.  Circles are drawn
       with small moving points along the perimeter. The intersections are rendered as  glowing  orbs.   Glowing
       orbs are rendered only when a perimeter point moves past the intersection point.

DISPLAY to get the default host and display number.

       XENVIRONMENT
               to  get  the  name  of  a  resource  file  that  overrides  the  global  resources  stored in the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

       Intermomentary accepts the following options:

       --num-discsdisccount(Default:85)
               Number of slowly moving and growing discs to use.  The more discs, the more CPU power.

       --draw-delaydelayms(Default:30000)
               Delay  in  ms  between drawing cycles.  More delay, slower (but smoother and less CPU intensive.)
               art.

       --max-ridersmaxrider(Default:40)
               Maximum number of 'riders', single dots moving around the edge of the discs.

       --max-radiusmaxradius(Default:100)
               Maximum possible radius of a disc.

       --fps   Display the current frame rate and CPU load.

       --visualvisual
               Specify which visual to use.  Legal values are the name of a  visual  class,  or  the  id  number
               (decimal or hex) of a specific visual.

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.
